Orlando shooting: Wife of gunman 'knew about massacre plan and begged him not to do it'

KNOWLEDGE: Noor Salman told cops she drove Mateen to Pulse to scope it out

Noor Salman allegedly drove husband Omar Mateen to scope out the Pulse nightclub – where he would carry out the worst mass shooting in US history.

The 30-year-old could also be prosecuted for failing to tell cops what the ISIS sympathiser was planning.

She could be charged with being an accessory to 49 counts of murder and 53 counts of attempted murder, a US law enforcement source said.

A federal grand jury has reportedly been convened and Salman could be charged today.

US Senator Angus King, a member of the senate intelligence committee, said: “It appears she had some knowledge of what was going on.

“She definitely is, I guess you would say, a person of interest right now and appears to be cooperating and can provide us with some important information.”

CARNAGE: FBI attempt to take bodies out of bullet-riddled Pulse nightclub

Salman allegedly told FBI agents she had tried to talk Mateen out of the attack.

Mateen, who was shot dead by police after a three hour standoff at the Pulse club early on Sunday, systematically picked-off club-goers, trapping some in the bathroom before unleashing a shower of bullets.

SURVIVOR: Angel Colon spoke of his terrifying ordeal at the hands of Mateen

He called police during his rampage to claim allegiance to various militant Islamist groups – including the Islamic State.

Investigators said he was probably self-radicalised and that there was no evidence that he received any instruction or aid from outside groups such as ISIS, although the deranged terror group has claimed responsibility for the attack.
